I have a 20g tank with 2 ryukins. Until recently everything was fine, except that I was a negligent in changing the filter for a few months. As a result, there was brown stuff (mulm?) all over the it (dense floss cartridge) and the holes in stationary filter were clogged with it too. I made the mistake of giving it a thorough cleaning and a changing the cartridge during a water change. It looks this caused the tank to start cycling. I tried soaking the old filter in water as I read that adding some mulm/bacteria back in would speed up the process, but it didn't seem to work. When I tested the water, I now have high ammonia 8.0 and low ph 6.0. NO2 and NO3 are zero.
After a couple of days the water turned cloudy white. I bought Ammo-lock and have been adding 10ml every other day for the past week as per the bottle. I've also been doing a 25% water change 2-3 times a week. i also added in some bio-support that i had left over from when I initially set up the tank a few years ago.
I am still feeding them twice a day - pellets in the morning and flakes in the afternoon (trying to use up my stock). The fish seem to be behaving normally.
How long can I expect this to continue? Is there anything else I should be doing?
